What's the best glue for gluing figures onto bases? A glue that allows those same figures to be removed at a later date without damaging either the figure or the base? The answer is probably here on the forum somewhere!

I use uhu for my figures, they don't tend to fall out when they fly off the pitch onto the floor. I've been told it's fairly easy to remove the figures in future but can't vouch for that.
That's no help whatsoever is it?
